60” Parshall flume

Developed in 1922 by Ralph L. Parshall for the United States Bureau of Reclamation, Parshall flumes are the most widely used type of flume for permanent flow monitoring installations. With wide flow ranges, resistance to submersion, simple flow meter calibration, and self-cleaning design, Parshall flumes are the first choice of many engineers and end-users.

Parshall flumes are sized by throat width and conform to standardized dimensions published in the U.S. Department of the Interior, Bureau of Reclamation, Water Measurement Manual.

Typical applications include:

• Sewage treatment plant influent and effluent
